public class HeaderFooter
HeaderFooter can contain Paragraph and Table child nodes. HeaderFooter is a section-level node and can only be a child of Section.
There can only be one HeaderFooter or each If Section does not have a HeaderFooter of a specific type or
the HeaderFooter has no child nodes, this header/footer is considered linked to
the header/footer of the same type of the previous section in Microsoft Word. When HeaderFooter contains at least one Paragraph, it is no longer
considered linked to previous in Microsoft Word. Example: Example: Example:

getChild | → inherited from CompositeNode |
public Node getChild(int nodeType, int index, boolean isDeep) |
If index is out of range, a null is returned.
nodeType
- A index
- Zero based index of the child node to select.
Negative indexes are also allowed and indicate access from the end,
that is -1 means the last node.isDeep

getChildNodes | → inherited from CompositeNode |
public NodeCollection getChildNodes(int nodeType, boolean isDeep) |
The collection of nodes returned by this method is always live.
A live collection is always in sync with the document. For example, if you selected all sections in a document and enumerate through the collection deleting the sections, the section is removed from the collection immediately when it is removed from the document.
nodeType
- A isDeep
- True to select from all child nodes recursively.
False to select only among immediate children. Example:
Shows how to extract images from a document, and save them to the local file system as individual files.Document doc = new Document(getMyDir() + "Images.docx"); // Get the collection of shapes from the document, // and save the image data of every shape with an image as a file to the local file system. NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true); int imageIndex = 0; for (Shape shape : (Iterable<Shape>) shapes) { if (shape.hasImage()) { // The image data of shapes may contain images of many possible image formats. // We can determine a file extension for each image automatically, based on its format. String imageFileName = MessageFormat.format("File.ExtractImages.{0}{1}", imageIndex, FileFormatUtil.imageTypeToExtension(shape.getImageData().getImageType())); shape.getImageData().save(getArtifactsDir() + imageFileName); imageIndex++; } }

Assert.assertEquals(24, body.getChildNodes().indexOf(body.getLastParagraph()));

If the node being inserted was created from another document, you should use
newChild
- The Node to insert.refChild
- The Node that is the reference node. The newNode is placed after the refNode. Example:

public java.lang.String toString(int saveFormat) throws java.lang.Exception |
saveFormat

In our document our list uses plain arabic numbers, // which start at three and ends at six if (paragraph.getListFormat().isListItem()) { System.out.println(MessageFormat.format("List item paragraph #{0}", listParaCount)); // This is the text we get when actually getting when we output this node to text format // The list labels are not included in this text output.
